Help me on biology plant worksheet that is about kalanchoes..?

All kalanchoes are members of the Crulaceae family. They are native to Southern Africa and Madagascar. You can propagate them using options b, c or d. You can not propagate them from root cuttings. They fix carbon using Crulacean Acid Metabolism (CAM). Succulents have a number of adaptations to conserve water. CAM plants keep their stomata closed during the day and open them at night when evaporation is less. This helps conserve water, Vegetative reproduction [In some plants, such as in Kalanchoe pinnata = Bryophyllum pinnatum) shown to the right, the leaves are notched along their margins. A special (marginal) meristem develops at the base of the leaf notches, each of which produces a new plantlet.] is sometimes triggered by stress. Leaves are fleshy -- they are modified to store water, their are hairs (tricomes) and wax on the leaf surfaces.
